I know these speakers extremely well. I have never owned them, but two of my best friends owned them and have tried them with various amplifiers. I am currently in the market for a pair of ProAc bookshelf speakers, and if I come across a Response 1/1S/1SC or a pair of Tablette Anniversaries, I will buy them immediately. These little speakers are something special. They may not be the most accurate, but they are certainly musical. With the exception of the 1SC (which has the newer ProAc house sound), the older speakers are classic ProAc. It's the audio equivalent of a warm hug and a cup of hot chocolate.
